ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 503,293, dated August 15, 1893.

Application filed July '7, 1893. $crial No. 479,853. (No model.)

To all whom it may concern:

Be itknown that I, EMANUEL PIsKo, a citi- Zen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Oigar-Bunching Machines, of which the following is a specification.

In the bunch-making machines heretofore in use, the tobacco was fed between rollers and supplied in compressed state toa bunchforming head which was provided with a cutter that severed a quantity of tobacco sufiicient for a filler and dropped the same onto a rolling apron where the cut-off charge of tobacco was rolled into a binder. The cutting off of the filler by a cuttenknife from the compressed tobacco fed to the bunching head is objectionable on many grounds, mainly however because the quantity out off in this manner is not a satisfactory substitute for a filler made by hand and does not produce cigars of the required degree of perfection.

As the main object of bunching machines 2 5 is to imitate as closely as possible the manipulations to which the tobacco is subjected when forming the filler by hand, it is obvious that the better this is accomplished, the more general will be their introduction.

0 The object of this invention is to construct a cigar-bunching machine in which the quantity of tobacco necessary for a filler is not cut oif by a cutting knife, but gripped and pulled away from the remaining quantity of tobacco and then dropped on or conducted to a suitable rolling mechanism, so that the tearing or splitting of the leaves by hand in forming long-filler bunches is closely imitated and a bunch produced that has nearly if not c entirely the characteristics of a hand-made bunch.

For this purpose my invention consists of a cigar-bunching machine, which comprises endless feed-belts between which the tobacco is fed forward, a vertically reciprocating retaining device for the tobacco, an oscillating cup provided with an independently swinging jaw by which the tobacco fed forward by the belts is gripped and torn away from the retaining device and then dropped by the oscillating motion and release of the gripping jaw onto the apron of the rolling mechanism, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, which form 5 5 a part of the specification, Figure 1, represents afront-elevation of my improvedcigar-bunching machine, parts of said figure being shown as broken off so as to show some of the operated parts behind the same. Fig. 2, isa 6-: vertical longitudinal section on line 2 2, Fig.

1. Fig. 2, is a detail front-view of the mechanism for intermittent motion to the feedbelts. Fig. 3, is a side-elevation of the machine, with a part of the frame broken off, to show portions of the actuating mechanism back of the same. Fig. 3 is a detail-section of the mechanism for moving the feed-belts. Fig. i is a plan-view of the machine, partly in horizontal section,on line 4 4.,Fig. 2. Figs. 7c 5, 6 and 7 are vertical transverse sections, drawn on a larger scale and showing the tobacco-separating parts of my improved machine in their successive positions of receiving, separating and dropping the quantity necessary for a filler; and Figs. 8 and 9 are detail sections of the rolling device, showing the same in the act of rolling the filler into a binder, and of delivering the bunch.

Similar letters of reference indicate corre- 8b sponding parts.

Referring to the drawings, A represents the supporting-frame of my improved cigarbunching machine, which frame consists of two upright standards A that are connected by transverse braces and tie-rods CL, as appears clearly from Figs. 1 and 4. On the supporting-frame A is arranged a stationary table B over which is conducted the lower endless feed-apron B which is mounted on guid- 9o ing and stretching rollers 12 I), that are arranged respectively'at opposite ends of the stationary table 13. The stretching roller b is provided with adj usting screws for the bearings of said roller, so that the proper degree 5 of tension can be imparted to the endless feed-apron B. At each side of the endless feed-apron B is arranged a rail B which proj cots above the level of the feed-apron l3 and which is capable of lateral adjustment by I00 means of transverse bolts b passing through lateral slots 11 of the rail B and clamp screws b, so that the rail can be adjusted near to or away from the endless apron B for the purpose ofproviding the required space for the tobacco required for different lengths of fillers. The tobacco to be worked up into fillers is spread over the feed-apron B by the attendant between the raised rails B and fed forward intermittently by the apron in the direction of the arrow, shown in Figs. 2 and 4. The means by which this intermittent motion is imparted to the feed-apron B will be fully described hereinafter.

Above the lower apron B and parallel thereto or nearly so, is arranged a second endless apron O, which is supported by a drivingroller (1 at one end and an adjustable stretching roller (1 at the other end. The feedapron O is made of less length than the lower feed-apron B, and serves to compress the tobacco that is spread over the lower feed apron B so as to feed the same with the apron B in forward direction toward the mechanism by which the filler is formed. The guide-roller d of the upper feed-apron Ois guided in fixed standards d of the supporting-frame,while the standards (I in which the stretching roller d is journaled, rests loosely on the side-rails B Intermittent motion is imparted to the upper feed-apron O by the driving roller 02 which is provided with radial pinsat each end, said pins engaging eyelets arranged in the edges of the feed-apron 0 so as to produce thereby a positive forward motion Without relying merely on the friction between the feed-apron and its driving and stretching rollers. The same positive feed-motion may be imparted to the lower feed-apron B by providing the driving-roller b with pins, which pins engage eyelets in the I edges of the belt B; Below the lower feedapron B and somewhat in front of the same, is arranged a bunch-rolling device E,- which may be made of any approved construction, that shown in the drawings consisting of a horizontally-reciprocating rolling table 8, to the front end of which one end of the rolling apron e is attached. The opposite end of the bunching apron e is attached to a transverse bar 6 of the supporting-frame A while the bunching-roller e is arranged below the apron and mounted in the U-shaped front portion of an intermittently-reciprocating slide-frame E which extends over both sides of the rolling table and is guided by means of'side-rails e in fixed ways 6 which are supported in brackets e that are attached to the front standards A of the supporting-frame A, as shown clearly in Fig. 1. The under side of the rolling table eis connected by a pivotlink e with an oscillating elbow-lever e which is pivoted to the frame A and provided with an anti-friction roller at its apex, said roller extending into the cam-groove of a cam 6 which is placed on a shaft S. The shaft S is supported in bearings at the lower part of the main-frame A. The cam-groove of the cam e is made in such a shape that the proper forward and backward motion is imparted to of the upper end of the return-lever c engages a fulcrumed lever e that is connected by a chain e that passes over aguideroller 6 with a hook e at the rear part of the slide-frame E, so that, by the engagement of the pin on the lug 6 with the end of the lever e a motion in an opposite direction is imparted to the slide-frame E and the bunching roller e The pin on the lug e extends in opposite direction to the pin on the lug 6 one pin being placed in the path of the downwardly-extending arm e 'of the slide-frame E, while the other pin is placed in the path The slide frame E receives a forward motion with the bunching roller'e mounted on the same and produces the rolling of the filler into the binder which is placed on that portion of the bunching apron which is over the rolling-table 6. At the front end of the rolling-table c is arranged, a spring-finger e to which the bunch is delivered after it is rolled .by the joint action ofthe rolling-apron e and bunching roller 6 supported on the sliding frame E the bunch being rolled in the pocket or bight of the rolling-apron formed in front of the bunching roller in the usual well known manner in cigar-bunching machines.

I do not confine myself to the specialconstruction of rolling mechanism, shown in the drawings, as any other approved mechanism can be used for this purpose.

Adjacent to and on a level with the frontend of the lower feed-apron B and vertically below the front-end of the other feed-apron (l is arranged a transverse horizontaltable or bridge F onto which the tobacco is fed by the feed-aprons B and C, it being then retained on said table by the serrated lower edge of a vertically reciprocating gate G, that is guided in upright ways g of the supporting frame A, said gate being provided with a projection or too 9 at its upper part which is acted upon by a cam g that presses the gatein downward direction and holds thereby the tobacco on the table F, until the cam g releases the toe g. As soon as the cam has passed the toe g, the gate G is raised again in its guide-ways by the action of a yoke-shaped oscillating lever g which is pivoted at its lower end to a transverse shaft 9 supported in bearings of the supporting frame. The upper end of the ]ever 9 is connected by a chain g that passes over a guide-roller g with a hook or eye 9 at the upper end of the gate G. Cams g located one on each side of 1116 cam g? act on the oscillating lever g and move the same in backward direction, so as to produce thereby the lifting of the gate G to a sufficient height so that the tobacco can be fed below its lower serrated edge in forward direction over the stationary table or bridge F. In front of the stationary table or bridge F is arranged a receiving-cup H which is pivoted by a transverse pivot-shaft h to fixed standards h of the supporting frame, so as to be readily tilted on said shaft. The lower front-edge of .the receiving cup H is in its normal position on a level with the upper surface of the stationary table or bridge F, as shown clearly in Figs. 2 and 5. At some distance from its edge the receiving cup His provided with atransverse lip 7t and above the same withagripping jaw H, which is pivoted to the side walls of the receiving cup H and which is acted upon by a fiat spring 71 attached to the rear-part of the receiving cup H. During the forward motion of the tobacco, produced by the feedbelts B and C, the gate G is in raised position and the gripping jaw H of the receiving-cup H is in open position on a level or nearly so with the lower serrated edge of the gate G, as shown in Figs. 2 and 5. A quantity of tobacco, suificient to form a filler, is moved forward by the feed-belt until it abuts against the fixed lip h in the receiving-cup H. The gate G is then moved in downward direction so as to press firmly on the tobacco on the table or bridge F. At the same time, the gripping-jaw H is pressed in downward direction by a vertically-reciproeating slide-piece H the lower end of which engages the front-end of the gripping-jaw at the proper time. The slide-piece H is guided by slots on suitable guide-studs 71 of the supporting frame, as shown in Figs. 5, 6 and 7, and is moved in downward direction by a cam h which engages a projecting lug 7t attached to the slide-piece H By the downward motion of the slide-piece H the gripping-jaw H is lowered and pressed toward the edge of the receiving cup H so as to firmly compress the tobacco fed into the cup and hold the same between the edges of the gripping-jaw Hand cup H. A tilting motion is next imparted to the receiving cup H by the pressure of the slide-piece II on the gripping-jaw H, the downward motion of the slide-piece 151 being continued by the cam its, so that the tobacco confined in the cup is separated or torn off from the main-portion of the tobacco which is firmly held between V the table or bridge F and the gate G, as shown in Fig. 6. The receiving cup H is connected by a pivot-pin its at one side with a vertically-reciprocating slide-piece H which is connected at its upper end with a curved leverarm it that is also pivoted to the transverse shaft g". The curved levenarm h is acted upon by a cam h on the upper cam-shaft of the machine, said cam being provided with an eccentric portion and a shoulder at the end of the eccentric porti0n,as shown in Fig. 2. At the moment when the lever-arm 7t leaves the eccentric portion of the cam h and drops on the concentric portion of the same, the connecting-rod II is moved in downward direction and imparts a quick tilting motion to the receiving cup H, as shown in Fig. 7. This tilting motion moves the cup away from the gripping-jaw H and permits the dropping of the entire quantity of tobacco which was separated or torn 0% by the joint action of the receiving-cup and grippingjaw H into the pocket or bight formed in the loose rolling apron e, as shown in Fig.7. As soon as the tobacco which forms the filler is deposited, it is rolled into the binder placed on. the apron and the bunch obtained is taken up to the spring-holder at the front-end of the rolling mechanism. The receiving-cup H is held in tilted position until the eccentric portion of the cam it gradually raises the curved lever-arm h and returns thereby the receiving-cup H into its initial position, with its receiving edge on a level with the stationary table. The next operation of feeding the tobacco, retaining the same on the table F by the gate G, compressing the projecting portion between the adjacent edge of the receiving cup and the gripping-jaw and the tearing off of the projecting portion by the oscillating motion imparted to the grippingjaw and cup and the dropping of the tobacco separated or torn off, is again repeated and thus one bunch after the other formed in regular manner, one at each revolution of the driving shaft.

The operative parts of my machinereceivc motion from a driving shaft S which is arranged in suitable bearings of the lower part of the supporting-frame A. To one end of the driving shaft S is applied afast and loose pulley in the usual manner on either one of which the belt is shifted in starting or stopping the machine. 011 the shaftS is arranged a pinion p which meshes with a gear-wheel 10 that is placed on the intermediate shaft S, which turns also in bearings of the lower part of the supporting frame A. To the intermediate shaft S is keyed the cam e by which reciprocating motion is imparted to the rolling table 6 and to the slide-frame E of the bunching roller a To the outer end of the shaft S is attached a motion-transmitting gear-wheel w of smaller diameter than the large gear-wheel w, the smaller gearwheel w meshing with an intermediate gearwheel 10", which turns a short shaft 20 on one of the standards of the frame A, the intermediate gear-wheel r0 meshing with a third gear-wheel w that is attached to the camshaft S which is supported in bearings at the upper part of the supporting frame A and on which are arranged the different cams by which motion is imparted to the reciprocating gate G, the receiving cup H and the grippingjaw II, as before described. A clutch p is arranged near the pinion p on the driving shaft S, said clutch 19 being ongaged by the rear'end of a fulcrumed lever L, the front-end of which is curved sidewise, so as to be within easy reach of the attendant, who is thereby readily enabled to start or stop the machine, by simply shifting the clutch-lever L andthrowing thereby the pinion 19 in or out of gear with the clutch-mechanism of the driving-shaft S.

The intermittent motion of the feed-belts l3 and G is produced by a camt'on the upper shaft S which cam engages the antifrictionroller of a fulcrumed elbow-lever t" .that is placed loosely on a transverse shaft 71 of the supporting frame, as shown in Figs. 2 and 3. The lower arm of the elbow-lever t" is connected by a link 1' with an oscillating arm 2' that is loosely placed on the shaft of the driv: ing rollerd of the upper feed-belt O, as shown in Figs; 2 and 3. To the hub of the loose arm 2' is: applied a chain t the lower endof which is connected to the hook-shaped end of a fiat spring 1' which is attached to the sup: porting frame A. On the shaft of the driving roller (1 are arranged sidewise of each other two ratchet-wheels i which are engaged by two pawls i pivoted to an oscillating keeper 2' on the lever-arm *F. The cam 2 imparts oscillating motion to the elbow-lever t" and to the elbow-arm t and the keeper 1' and transmits thereby-by the pawls t and the ratchet-wheels 1' intermittent. rotary motion to a pinion 'i on the shaft of the feed-roller d and thereby an intermittent forward Il'lO". tion to the upper feed-belt G: The pinion 2' meshes with the pinion 2' on the shaft of the lower feed-roller b and imparts thereby intermittent motion to the lower feed-belt B, said, motion being sufficient to feed forward the quantity of :tobacco required for a filler. After the cam't' has passed the antifriction roller of the elbow-lever l, the'oscillating arm 6 with the keeper t is returned by the spring i to its former position so that the pawls are moved over the .teeth of the ratchet-wheels and without engaging the same, while the. belts are retained in position ready for the next forward motion of the feed-belts, when the cam 11 engages at the next rotation on the shaft S the elbow lever 01 and transmits by the intermediate pawl and ratchet mechanism' described intermittent forward motion 7 into thepath of the upper arm of the .elbow lever t" and serves to arrest the motion of the latter in one direction, while the came imparts oscillating motion to the upper arm of the elbow-lever t" in the other direction. The more the stop cone k is adjusted in inward direction the smaller will be the throw of the elbow-lever t" and the smaller will be the feed-' motion of the feed-belts, while the more the stop cone k is moved away from the elbowlever z" the greater will be the throw of the elbow-lever z" and the greater the feed-motion lated according to the quantity of tobacco desired for the filler andbunch to be produced.

The operation of my improved cigar-bunching machine is as follows: The tobacco from which the fillersare to bemadgis-spread over the lower feed-belt in such a manner that the required thickness of the filler is obtained. The machine is then started and the tobacco fed successively to the working parts of the machine, care being taken that successively new quantities of tobacco are spread on the lower feed-belt, so that the continuous operation ofthe machine can be kept up. As the tobacco is passed under the vfeed-belt, it is fed forward by the slight compression imparted by the belts onto the fixedtable or bridge F on whichthe tobacco isfirmly pressed by the serrated lower edge of the descending gate G, a quantity sufficient for a filler projecting in front of the same into the receiving cup H. Thisprojecting portion is taken hold of by the gripping-jaw H and cup H and torn offin imitation to the motion of the hands in separating and tearing off tobacco for a long filler, it being then tilted withthe cup H, dropped onto the rolling mechanism, where it is rolled with the binder'into abun'ch in the usual well-known manner and then placed intothe mold. The position of the cams on thedriving shafts of the machine is so arranged that all the different motions are produced at the proper time and that ateach r0- tation of the driving shaft a bunch is produced.

The advantages of my cigar-bunching machine are,thata bunch is obtained which resembles much closer a handmade bunch, than a bench in which the filler is cutoff by a cutting knife, so that cigars are finally obtained which resemble in a high degree hand-made cigars, inasmuch-as the fillers contained in the same are more like hand-made fillers.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with intermittently actuated feed-belts, of a stationary table or bridge in front of and on a level with the lower feed belt, avertically reci procatin g gate having a serrated lower edge, a receiving cup arranged in front of said table, a spring-actuated grippingjaw pivoted to the receivingcnp, means for pressing said gripping-jaw on the tobacco projecting beyond the gate, and means for tilting the cup after the grippingjaw is moved in downward direction, so as to separate or tear off a quantity of tobacco necessary for a filler, substantially as set forth.

3. The combination, with intermittentlyactnated feed belts, a stationary table or bridge in front of and on a level with the lower feed-belt, a vertically-guided gate having a serrated lower edge, means for impartceiving-cup pivoted in front of the stationary table or bridge and provided with a fixed lip or abutment at some distance from its edge, a spring-actuated gripping-jaw pivoted to the receiving cup above said lip, and a rolling mechanism arranged below the receiving cup for delivering thereon the tobacco torn off by the joint action of the gripping jaw and cup, substantially as set forth.

4. The combination, of intermittently-actulng reciprocating motion to said gate, a re" ated feed-belts, a stationary table or bridge in front of the lower feed-belt, a verticallyguided gate having a serrated lower edge, means for imparting reciprocating motion to said gate, a pivoted receiving cup in front of the stationary table provided with a lip or abutment at some distance from its edge, a spring-actuated gripping-jaw pivoted to the receiving-cup, means for lowering the gripping jaw and pressing the same on the tobacco projecting beyond the gate and table, means for tilting the receiving cup so as to separate or tear off the projecting quantity of tobacco and a rolling mechanism below the tilting cup 'so as to form a bunch after the quantity of tobacco necessary for a filler is dropped into the pocket or bight of the apron of said rolling mechanism, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
